2.3.2.3. 100GE PCS with Optional RS-FEC Hardware Design Example Components
- E-Tile Hard IP for Ethernet Intel FPGA IP core.
- PCS packet generator and checker that coordinates the programming of the IP core, packet generation, and verify the packets.
- IOPLL to generate a 100 MHz clock from a 50 MHz input clock to the hardware design example.
- JTAG controller that communicates with the System Console. You communicate with the client logic through the System Console.
The hardware design example test initiates media-independent interface (MII) packet transmission from packet generator to the IP core. The packet generator supports incremental packet mode, fixed-size packet mode, and random packet content mode. Once reset is completed, the packet generator generates the number of packets requested to the IP core. The IP core transfers the packets through internal PMA loopback to the packet generator and checker for verification. This test only works with internal PMA loopback mode.
